Mathematical Modelling of Cooling and Prediction of Mechanical Properties of Shapes After Hot Rolling

Popis výsledku v původním jazyce

The work described in this paper had several objectives: charting the temperature field after the last rolling pass by means of mathematical modelling and in-situ temperature measurement, finding cooling curves for various sets of operating conditions and predicting mechanical properties (impact energy, yield and ultimate strengths) for selected sections:flat and angle bars. The temperature field after hot rolling was mapped using inverse analysis in FormFEM program on the basis of the known surface temperature vs. time curve for the bar after rolling. Thermal properties of the steels were explored in a laboratory experiment. For mechanical properties to be predicted in TTSteel program, the CCT diagram of the steel was constructed. Mechanical properties of the rolled products were determined for various cooling methods: immediately behind the rolling stand or on the cooling bed. An optimum cooling schedule and production guidelines were drafted on the basis of the collected data
